JOINING MEMBER FOR AUTOMOBILE WINDOWS.

Application filed August 17, 1928. Serial No. 300,181.

In the manufacture of automobile windows, it is customary to form the inside sill and jamb members of rolled sheet metal, with the jamb member resting on the sill member. These pieces are put in place as part of the finishing operation, and it is difiicult to make a good joint between them. I have found that if a properly shaped block of sponge rubber is provided, it will serve to make a neat, tight fit between the two parts, which can be easily assembled, due to the compressibility of the sponge rubber.

This invention can readily be understood by reference to the illustrative example shown in the accompanying drawings, in which Fig. 1 is a perspective sectional view of a portion of a Window; Fig. 2 is a perspective view of the sponge rubber block used in Fig. 1, and Fig. 3 is a section on line 3-3 of Fig. 2.

In Fig. 1 the numeral designates a portion of an automobile door, for example, on the inside of which is provided a sill member 12, and two jamb members such as shown at 14. Each of these is formed of rolled or bent sheet metal. As a means of making a good connection between these parts, I supply a block 16, of sponge rubber. The block 16 has an upper portion 18 shaped to fit inside of the member 14:. The lower part of block 16 substantially continues the contour of the outside of member 14, but the shoulder where the two parts meet may be provided with a flange 20 running at least part way round its periphery to prevent the block from being forced up inside member 1 1, though this is not mess sary. The under surface of block 16 is preferably shaped to fit the contour of sill member 12.

In assembling the window, member 12 is attached, and then after block 16 has been inserted in member 14, either the upper end of the latter may be put in place and the bottom end pushed in,which may be done either along or transverse the length of member 12, for the block will be readily compressible; or the bottom end may be put in position and then such jamb member may; be forced down by compressing the block 16,

to permit the upper end to be moved into place.

IVhat I claim is: I

1. A joining member for automobile window contruction comprising a block of compressible sponge rubber with an upper part adapted to fit inside of a jamb member, a lower part adapted to continue the contour of the outside of such jamb member, and a shoulder connecting the two adapted to receive the end of the jamb member. 1

2. A structure as specified in claim 1, in which the block is provided with a flange adjacent the shoulder to prevent the lower part of the block from being forced into the jambmember.
